Dodge 2004 HB Durango - Manual (Page 256)

• Trailer brakes are recommended for trailers over 1,000
lbs (454 kg) and required for trailers in excess of 2,000
lbs. (907 kg).
• Use an approved trailer harness and connector. If a
hitch is ordered, the proper wiring will be provided.
• When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
• Make certain that the load is secured in the trailer and
will not shift during travel. When trailering cargo that
cannot be fully secured, dynamic load shifts can occur
that may be difficult for the driver to control.
• All trailer hitches should be professionally installed on
your vehicle.
• Safety chains must always be used between your
vehicle and trailer.
• Connect trailer lighting and brakes using factory har-
nesses only. Do not cut or splice any wiring to the
brake circuits.
Trailer and Tongue Weight
Gross Trailer Weight (GTW) means the maximum allow-
able weight of the trailer plus the weight of all cargo and
equipment loaded on the trailer when in actual under-
way towing condition. The recommended way to mea-
sure GTW is to put your fully loaded trailer on a vehicle
scale. The entire weight of the trailer must be supported
by the scale.
Tongue Weight is the weight placed on the vehicle’s
trailer hitch by the trailer. Always load a trailer with 60%
to 65% of the weight in the front of the trailer. This places
10% to 15% of the GTW on the tow hitch of your vehicle.
